The equation would be x+3x(10+2x)=142
The sides are 22cm , 54cm and 66 cm.
Answer:
The answer is C. 6.4 X 8 in
Step-by-step explanation:
If the scale factor from the original to the trimmed photo is 5:4
The statement above just means the scale of the old dimension is 5 while the scale of the new dimension is 4.
To get the new dimensions, multiply each of the old dimensions by 4/5
4/5 X 10 = 8
4/5 X 8 = 6.4
Therefore the new dimension is 6.4 X 8 in
Oh god not again.....................
Use a proportion.
A ratio of 44 blue to 33 yellow is the same as a ratio of 4 blue to 3 yellow.
Since you are told the total of cards, 84, add 3 + 4 = 7
In the deck, the cards are int he ratio of 4 blue to 3 yellow to 7 total.
4 blue to 7 total = x blue to 84 total
4/7 = x/84
7x = 4 * 84
x = 4 * 12
x = 48
There are 48 blue cards.
99
because 0.49 is less than 0.5(0), we round it down.
